ROBERT EDW'ARD JACKSON AND EDWIN MILTON JENKINS, OF PRINCETON, WEST VIRGINIA.

FLUE-BLOWER.

Application filed September To all w item it may concern:

Be it known that we, Bonner E. JACKSON and EDWIN M. JENKINS, citizens of the United States, residing at Princeton, in the county of Mercer and State of est Virginia, have invented certain new and useful Improvements in Flue-Blowers, of which the following is a specification.

This invention relates to newand useful improvements in flue blowers for blowing cinders and other substances from flues and more particularly to an apparatus for use in locomotive fiues.

An important object of the invention is to provide means whereby cinders or other substances may be blown from the fines of a boiler without drawing the fire.

A further object of the invention is to provide means whereby any designated flue of the boiler may be blown free from cinders or any other material which may have been deposited therein independently of the remaining fiues of the boiler.

A further object of the invention is to provide means for indicating which of the flues is being cleaned.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same- Figure 1 is a front elevation of our device detached from the boiler, the approximate relation of the boiler parts being shown.

Fig. 2 is a section taken through the boiler showing our device in elevation.

Fig. 3 is a fragmentary plan view partly in section of our invention.

Fig. 4 is an enlarged section taken on line 4-4 of Fig. 3.

Fig. 5 is a longitudinal section through the feed apparatus.

Figs. 6 and 7 are detail views, illustrating the spider.

Fig. 8 is a front elevation of the indicator and,

Fig. 9 is, a side elevation thereof.

In the drawings, wherein for the purpose of illustration is shown a preferred embodi-' ment of our invention, the numeral 7 desig nates a boiler as a whole, and the numeral 8 indicates the outer wall thereof.

Secured to the outer Wall of the boiler, as

Specification of Letters Patent.

by means of rivets 9 or the like, is a manifold 10. The manifold 10 is connected with a suitable source of steam supply 11, as for example, the blower pipe of a locomotive, by means of a suitable conduit 12, having a valve 13 therein, to govern the supply of steam to the manifold 10.

The interior of the manifold 10 is provided with chambers 15, inner ends with a flange 16, secured to the chambers 15 by means of flanges 16, c0- acting with the flanges 1.6, are tubular casings 17, having inner or free ends closed and supported by brackets 17, secured to the wall 8' of the boiler. The casings 17 and chambers 15 correspond in number and arrangement with the number of rows of tubes 14, formed in the boiler and adjacent each tube of the row, the tubular casings 17 are provided with outlets 18, adapted to receive pipes 19, which extend into the flues for a short distance. Mounted in journals 20, formed in the wall of the manifold 10, are rotatable shafts 21, provided upon their inner end with spiders 22, affording openings 23, secured to the spiders 22 is a rotary valve 24, provided with openings 25. The openings 25 of the valve are spirally arranged so that they are successively brought into engagement with the various outlets 18 of the tubular casings 17. Adjacent each opening, the valy e 24 is provided with an enlargement 26, affording grooves 27 for the reception of packing rings.

Each of the chamberslt") is provided with an intake opening 28, closed by a valve 29, the stem 30 of which extends outwardly through the wall of the manifold 10 and is provided with a wheel or handle 31. It will readily be seen that steam may be selectively admitted to any of the chambers 15, and passing therethrough, enters the valve 24 and thence through openings 25 and outlets 18, to the flues of the boiler.

The outer ends of the rotatable shafts 21 pass through a packing gland 32, and are provided with a disk 33, having notches 34 formed therein. These notches are successively numbered and correspond to the positions of the openings 25 in the valve 24. Mounted upon a suitable bracket 35 is a tubular head 36, having a spring 37 mounted therein. This spring 37 acts against a plunger 38, which is adapted to engage in the notches 34 of the disk 33,

provided upon their The operation of our device is as follows:

Steam is admitted to the manifold 10 from the pipe 11 by means of the conduit v12. In event of a flue clogging the indicator of this set of flues is set to the number of the flue which has become clogged, thus alining the opening 25 of the valve 24 with the outlet 18 and pipe 19 leading to this particular fine. The valve 29 is now opened, admitting steam to the casing 15 and the flue will be cleaned by the forceof the jet directed th erethrough.

It is to be understood that the form of our invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims. 7 i

What we claim is: j

1. In a flue blower in combination with a boiler provided with flues, a manifold secured to the outer wall of the boiler and connected with a suitable force of "fluid pressure supply, a plurality of chambers formed within said manifold and provided upon their inner ends with flanges, tubular casings secured to said flanges and provided with outlets adapted to project for a short distance into the fines of the boiler, journals formed in the wall of said manifold rotatable shaftsmountcd in cured to said spiders and means for controlling the admission of fluid pressure to each of said chambers.

2. In a'flue blo-wer'in combination with a boiler provided with flues arranged in rows and having a smoke box, a manifold secured upon the outer wall of the furnace, a plulrality of chambers formed within the manifold and having their inner ends projecting within the smoke box, said chambers corresponding in number and arrangement to the rows of flues in said boiler, tubular casings secured to said chambers and extending along the rows of fines, and an outlet formed in said casings adjacent each fine of each row a valve within each of said casings provided with openings adapted to register with said outlets, means for rotating said valves, comprising rotatable shafts provided in said manifold and having one end connected to said valves and the other projecting with out the-manifold and provided with a disk and means for indicating which of said openings is in registry with its outlets comprising, notches formed in said disk corresponding in number and arrangement to the open ings in the valve to which it is secured and an indicating member adapted to engage in said notches.

In testimony whereof we afliifour signatures in presence of two witnesses.
